Hereinafter, exemplary embodiments will be described in detail withreference to accompanying drawings.

FIG. 1 is a schematic diagram of a structure which is configured tosharing content information, according to an exemplary embodiment.

According to the present exemplary embodiment, an external device 110may transmit information which relates to at least one contentreproduced on the external device 110 to a device 100.

For example, the external device 110 may broadcast a packet whichincludes tag information 120, such as, for example, a title of a songplayed by the external device 110, via short-range wirelesscommunication. In particular, broadcasting of the packet via short-rangewireless communication may refer to transmission of the packet so thatan arbitrary device may receive the packet.

In an exemplary embodiment, the packet includes the tag information 120,that is, the tag information 120 is inserted in a field of the packet.For example, the tag information 120 may be inserted into at least onefrom among a service set identifier (SSID) field in a beacon frame and avendor specific information element (VSIE) field of IEEE 802.

The tag information 120 may include information which relates tocontent. In particular, the information about the content denotesinformation which relates to content provided on the device. Forexample, if music content is provided on the device, the tag information120 may include, for example, any one or more of a title, an artist'sname, an album's name, and a producer's name of the song played on thedevice. As another example, if game content is provided on the device,the tag information 120 may include scores which relate to the gamecontent.

Short-range wireless communication is a wireless communication methodwhich is capable of transmitting/receiving data within a relativelyshort distance. According to the present exemplary embodiment, thedevice 100 may directly receive the packet which is transmitted from theexternal device 110, or the device 100 may receive the packet via arepeater. For example, when the external device 110 transmits the taginformation 120 to an access point (AP) connected via a wirelessfidelity (WiFi) communication method in infrastructure mode, the AP mayinsert the tag information 120 into an SSID and broadcast the taginformation 120. However, the exemplary embodiments are not limitedthereto.

If a connection of near field communication between the external device110 and the device 100 does not include the repeater, the communicationbetween the external device 110 and the device 100 may be performed byusing a direct communication method. Direct communication betweendevices denotes that the devices may transmit/receive data directlyto/from each other. The direct communication method between the devicesmay include any one or more of Bluetooth communication, ultra wideband(UWV) communication, ZigBee communication, and WiFi direct communicationincluded in wireless LAN communication in ad-hoc mode. However, theexemplary embodiments are not limited to the above examples. That is,the direct communication method between devices may be referred to asany one or more of a machine-to-machine (M2M) communication method, adevice-to-device (D2D) communication method, and a peer-to-peer (P2P)communication method.

The device 100 may receive information about content from at least oneexternal device 110. The device 100 which receives the information aboutthe content may provide a user with the content by using the informationabout the content. In particular, the device 100 requests, from theserver, an object which relates to using the service providing thecontent, and may receive the object for using the service from theserver. The device 100 displays the object for using the service, andmay provide the user with the service by using the displayed object.

For example, the device 100 may receive the tag information 120 that isbroadcasted by the external device 110. The device 100 that receives thetag information 120 may provide the user with the content by using thetag information 120. For example, when the device 100 receives the taginformation 120 which includes a title of a song, the device 100 mayreproduce a sound source corresponding to the title. In particular, thedevice 100 may transmit, to the server, a request for a sound sourcereproduction service in order to provide the service of reproducing thesound source, and may receive an object for using the sound sourcereproduction service.

In the exemplary embodiments, the device 100 and the external device 110are distinguished by their operations according to the exemplaryembodiments, and a device may perform as both the device 100 and theexternal device 110. In particular, the device 100 may receive the taginformation 120, and at the same time, the device 100 may broadcast taginformation which includes information about content provided via thedevice 100.

The device 100 and the external device 110 are capable of performingdata transmission. The device 100 and the external device 110 may be thesame kind of devices or different kinds of devices. The device 100 andthe external device 110 may be any one or more of various devices, forexample, mobile phones, smartphones, laptop computers, tablet computers,handheld PCs, electronic book terminals, digital broadcasting terminals,personal digital assistants (PDAs), portable multimedia players (PMPs),navigation systems, and smart televisions (TVs). However, the device 100and the external device 110 are not limited thereto.

FIG. 2 is a flowchart which illustrates processes for broadcastingcontent information from the external device 110.

In operation S210, the external device 110 may generate tag informationwhich relates to content provided via the external device 110.

The external device 110 may generate the tag information which relatesto the content provided to the user of the external device 110. Inparticular, the content provided to the user may include any one or moreof various contents, for example, movies, music, games, and exercisemanagement services.

For example, if movie content is reproduced on the external device 110,the external device 110 may generate tag information which includes anyone or more of a title of the movie, a genre of the movie, and names ofactors starring in the movie. In this case, the external device 110 maygenerate tag information which includes information extracted frommetadata of the reproduced movie content.

Then, in operation S220, the external device 110 may insert the taginformation in a field of a packet that is transmittable via short-rangewireless communication. For example, the tag information may be insertedin an SSID field or a VSIE field.

Then, in operation S230, the external device 110 may broadcast thepacket in which the tag information is inserted via short-range wirelesscommunication.

According to the present exemplary embodiment, the device 100 maydirectly receive the packet which is transmitted from the externaldevice 110, or the device 100 may receive the packet via a repeater. Forexample, when the external device 110 transmits the tag information toan AP which is connected via a WiFi communication method ininfrastructure mode, the AP may insert the tag information in an SSIDand broadcast the tag information. However, the exemplary embodimentsare not limited thereto.

If a connection of near field communication, short-range communication,or short distance communication between the external device 110 and thedevice 100 does not include the repeater, the communication between theexternal device 110 and the device 100 may be performed by using adirect communication method. Direct communication between devicesdenotes that the devices may transmit/receive data directly to/from eachother. The direct communication method between the devices may includeany one or more of Bluetooth communication, UWV communication, ZigBeecommunication, and WiFi direct communication included in wireless LANcommunication in ad-hoc mode. However, the exemplary embodiments are notlimited to the above examples.

FIG. 3 is a diagram which illustrates processes for inserting taginformation which includes content information in a packet via theexternal device 110, according to an exemplary embodiment.

The external device 110 may generate tag information 350 by extractingdata from content 310 which is provided on the external device 110. Inparticular, the content 310 provided on the external device 110 mayinclude any one or more of various types of content, such as, forexample, music content, game content, e-Book content, and movie content.

If the content provided on the external device 110 includes musiccontent, the external device 110 may generate the tag information 350which includes, for example, any one or more of a title, an artist'sname, an album's name, and a producer's name of the song which isplayable on the external device 110.

Further, if the content provided on the external device 110 includesgame content, the external device 110 may generate the tag information350 which includes score information of the game provided on theexternal device 110.

Still further, if the content provided on the external device 110includes e-Book content, the external device 110 may generate the taginformation 350 which includes any one or more of a title, an author,and a genre of the e-Book provided on the external device 110.

In addition, if the content provided on external device 110 includesmovie content, the external device 110 may generate the tag information350 which includes, for example, any one or more of a title, a genre,and actors starring in the movie provided on the external device 110.

However, one or more exemplary embodiments are not limited to the aboveexamples.

According to an exemplary embodiment, the tag information 350 mayinclude static data 320 and/or dynamic data 330.

According to the present exemplary embodiment, the static data 320 maydenote data that may be defined based on the content, for example, anyone or more of a category of the content, a genre of the content, andinformation stored in metadata of the content.

Further, according to the present exemplary embodiment, the dynamic data330 may denote data that may vary based on the user or generation of thetag information, for example, a rank and/or a history of the user usingthe content.

The tag information 350 may not necessarily include both the static data320 and the dynamic data 330. The tag information 350 may include one ofthe static data 320 and the dynamic data 330, or both of them.

The external device 110 may insert the generated tag information 350 ina packet 340 that is broadcasted via short-range wireless communication.In particular, the static data 320 and the dynamic data 330 may beinserted in different fields of the packet 340, according to the presentexemplary embodiment.

FIG. 4 is a flowchart which illustrates processes for sharing contentinformation by the device 100, according to an exemplary embodiment.

In operation S405, the device 100 may receive, from an external device,information about at least one content which is reproduced by theexternal device 110.

In particular, the information about the content may include informationthat identifies the content. For example, if the content includes musiccontent, the information about the content may include a title of themusic. However, the exemplary embodiments are not limited thereto.

According to the present exemplary embodiment, the information about thecontent may include tag information about the content. For example, theinformation about the content may include tag information which isextracted from metadata of the content.

According to the present exemplary embodiment, the information about thecontent may be included in the packet that is broadcasted from theexternal device 110 via short-range wireless communication. For example,the information about the content may be inserted in an SSID or a VSIEbroadcasted from the external device 110, and then transmitted. In thiscase, the device 100 receives the packet that is broadcasted from theexternal device 110 via short-range wireless communication, and mayextract the information about at least one piece of content from thepacket. In the specification, the term ‘broadcast’ refers totransmission of information or a message from one place or one device toa plurality of devices or an arbitrary device.

Then, in operation S415, the device 100 may request, from a server, aservice which relates to the information about the content which isreceived from the external device 110. For example, if the informationabout the content includes a title of at least one moving picture, thedevice 100 may request a service about the moving picture reproductionfrom the server.

In particular, according to the present exemplary embodiment, when thedevice 100 requests the service from the server, the device 100 maytransmit the information about the content to the server. In response tothe request which is received from the device 100, the server maygenerate an object for using the service which relates to theinformation about the content. For example, if the server receives theinformation about content including song titles such as “Arirang” or“Gangnam Style”, the server may generate an object which facilitates acapability of the device 100 to reproduce the songs “Arirang” and“Gangnam Style”.

Further, according to another exemplary embodiment, the device 100 maydetermine, from among a plurality of applications which are installed inthe device 100, an application which is usable for reproducing thecontent which is reproduced on the external device 110. In particular,when device 100 requests the service from the server, the device 100 maytransmit information about content, which includes information which isusable for identifying a determined application. The server may generatean object for using the service by using an application that mayreproduce the content, from among a plurality of applications which areinstalled in the device 100, based on the information which is usablefor identifying the application.

For example, if the external device 110 reproduces the music through “amusic playing service 1” by using “a music playing application 1” andthe device 100 includes “a music playing application 2” that may providethe user with “a music playing service 2”, the server may generate anobject for using the music playing service via the “music playingservice 2”.

Further, according to another exemplary embodiment, the device 100 mayidentify a service account that has an authorization to use the contentreproduced on the external device 110. The device 100 may request, fromthe server, a service that requires a log-in registration, by using theidentified service account.

In addition, referring also to FIG. 14, if there is no service accounthaving an authorization to use the content reproduced on the externaldevice 110, the device 100 may output a user interface for buying ausage authority via an output unit (also referred to herein as an“output component”) 1320 of the device 100. For example, if the externaldevice 110 reproduces music and the device 100 does not have a serviceaccount for reproducing music, the device 100 may output a userinterface for buying a usage authority of the lowest price forreproducing the music.

Then, in operation S425, the device 100 receives the object for usingthe service from the server, and in operation S435, the device 100outputs the object. The device 100 may provide the user with the servicewhich relates to the information about the content which is receivedfrom the external device 110 by using the output object.

According to another exemplary embodiment, the device 100 may receiveinformation which is usable for identifying the external device 110,instead of the information about the content, in operation S405. Then,the device 100 may request a service which relates to the externaldevice 110 from the server in operation S415. In particular, the servermay acquire information about content reproduced on the external device110 or information about the service provided on the external device110. For example, the external device 110 may periodically updateinformation about the content reproduced on the external device 110 orthe service provided on the external device 110 to the server. Theserver generates an object for reproducing the content reproduced on theexternal device 110, and transfers the object to the device 100. Thedevice 100 may output the object which is received from the server, andmay provide the user with the service by using the output object.

FIG. 5 is a flowchart which illustrates processes for reproducingcontent by using tag information in the device 100, according to anexemplary embodiment.

In operation S410, the device 100 may receive a packet that isbroadcasted from the external device 110 via the wireless communication.

According to the exemplary embodiment, the device 100 may broadcast taginformation about the content provided via the device 100 based on auser's selection via short-range wireless communication. According tothe present exemplary embodiment, the device 100 may perform operationsS410, S420, S430, and S440 in a case in which the tag information isbroadcasted. In particular, in order to receive the tag information fromthe external device 110, the user of the device 100 may broadcast thetag information which is generated from the content reproduced on thedevice 100.

Then, in operation S420, the device 100 may acquire and/or extract thetag information from the packet.
